In recent years, activities aimed at building a carbon-free society have become active by reducing greenhouse gases. Customers such as companies are trying to formulate plans for greenhouse gas reductions by the final target year. However, it is not easy to predict how much greenhouse gas can be reduced in the future, and it is difficult to set a target plan for the amount of greenhouse gas reduction.

Therefore, in the present embodiment, a system is provided to support the customer to set a target plan for the amount of greenhouse gas reduction.

FIG. 1 shows an example of a functional block of the determination device 100 according to the present embodiment. The determination device 100 includes a reception unit 102, a determination unit 104, an output unit 106, and a storage unit 110. The determination device 100 determines the amount of greenhouse gas reduction. The storage unit 110 stores various programs for operating the determination device 100.

The reception unit 102 refers to a database that manages at least one of the customer's annual power consumption (kWh) in the previous year, GHG emissions in the previous year, and GHG target reduction in the target year. The customer may accept at least one of the previous year's annual power consumption (kWh), the previous year's GHG emissions, and the target year's GHG target reduction.

The determination unit 104 shows an example of a first determination unit, a second determination unit, and a third determination unit. The determination unit 104 determines the target reduction amount for each target year up to the target year according to a predetermined algorithm based on the target reduction amount. The determination unit 104 may determine the target reduction amount for each target year so that the target reduction amount for each target year up to the target year is the same amount. The target year may be one year, two years, three years, four years, or five years up to the target year.

The decision unit 104 determines the GHG for each target year so as to connect the reduction amount in the start year and the reduction amount in the final target year with at least one straight line having a predetermined slope or a predetermined parabola. The target reduction amount may be determined. The decision unit 104 sets the target reduction amount in the intermediate year (for example, 2030) between the start year and the final target year by 46% compared to the base year, and the target reduction amount in the final target year by 100 compared to the base year. %, Between the reduction amount of the previous year (0%) and the reduction amount of the interim year (46%), the reduction amount of the interim year (46%), and the reduction amount of the final target year (100%). The target reduction amount of GHG for each year may be determined so as to connect with and with a predetermined straight line of inclination or a predetermined parabolic line, respectively. The reception unit 102 may accept from the customer the modification of the target reduction amount of GHG for each target year determined by the determination unit 104 according to a predetermined algorithm.

The reception unit 102 receives the certainty reduction amount, which is the reduction amount of GHG caused by the activity with certainty that leads to the reduction of GHG, for each target year up to the target year. The certainty reduction amount is the reduction amount of GHG caused by the activity that can be surely realized with a probability of almost 100%.

The certainty reduction amount may include the greenhouse gas reduction amount realized by the activities carried out in the property owned by the group to which the customer belongs. The group to which the customer belongs may be a corporate group related to the customer, and includes, for example, group companies such as a head office, a subsidiary, and an affiliated company. The amount of certainty reduction is the amount of greenhouse gas reduction by energy saving activities carried out in the property owned by the group to which the customer belongs, and the reduction of greenhouse gas by the energy creation activity carried out in the property owned by the group to which the customer belongs. It may contain at least one of the quantities. A reverse auction may be used to select a business operator to receive services in order to realize energy saving activities or energy creation activities.

The certainty reduction amount may include the reduction amount of greenhouse gas reduced by using the electric power supplied from the renewable energy power generation facility installed in the property owned by the group to which the customer belongs. The renewable energy power generation facility may be a solar power generation facility, a wind power generation facility, or the like. The certainty reduction amount includes the GHG reduction amount corresponding to the power generation amount by the renewable energy power generation facility calculated based on the installation area where the renewable energy power generation facility can be installed on the site owned by the group to which the customer belongs. The certainty reduction amount includes, for example, the reduction amount of GHG corresponding to the power generation amount by the photovoltaic power generation facility calculated based on the installation area where the photovoltaic power generation facility can be installed on the site owned by the group to which the customer belongs. The amount of certainty reduction is the amount of power generated by multiplying the area of the roof of the building owned by the group to which the customer belongs by a predetermined coefficient. The amount of reduction may be included.

The amount of certainty reduction is determined by deciding to install a renewable energy power generation facility when the installation cost when setting up a renewable energy power generation facility on the site owned by the customer is lower than the target price unit price, and the renewable energy. It may include the amount of greenhouse gas reductions that are reduced by using the power supplied by the power generation facility. The installation cost of renewable energy power generation equipment may be determined by a reverse auction. The target price unit price is calculated by (introduction cost of renewable energy power generation equipment (installation cost + maintenance cost)) ÷ (total power generation amount by renewable energy power generation equipment). The maintenance cost includes the operation management and maintenance cost, and the power conditioner cost (equipment replacement cost every 10 years according to the contract period). The renewable energy levy and the power generation side basic charge may be added to the target price unit price. However, if the solar power generation equipment owned by the customer is installed in the property owned by the group to which the customer belongs and self-consignment is performed without using the grid, the renewable energy levy does not have to be added to the target price unit price. .. In the case of electricity purchased under the FIT system, FIP system, and non-FIT system, electricity of less than 10 kW or electricity consumed by the self (excluding the amount of power that is not actually consumed and becomes surplus and reverse power flow). The basic charge on the power generation side does not have to be added to the target price unit price.

The reception unit 102 may determine whether the received certainty reduction amount satisfies the condition preset for the customer who sets the target reduction amount. The output unit 106 indicates that if the certainty reduction amount for each year received by the reception unit 102 does not satisfy the predetermined condition for the customer, the certainty reduction amount does not satisfy the predetermined condition. May be output to the customer. The reception department 102 is a company working on SBT (Science Based Targets) that sets the target reduction amount of RE100 or the level of GHG reduction specified by the Paris Agreement, which aims to cover the business with 100% renewable energy. If so, it may be determined whether the certainty reduction amount for each year satisfies the condition of the target reduction amount specified in RE100 or SBT.

The output unit 106 indicates that the certainty reduction amount does not satisfy the predetermined condition when the certainty reduction amount received by the reception unit 102 does not satisfy the predetermined condition for the customer who sets the target reduction amount. The indicated message may be output to the customer.

The decision unit 104 determines the remaining reduction amount of greenhouse gas required to achieve the target reduction amount for each target year based on the target reduction amount for each target year and the certainty reduction amount for each target year. To decide. The determination unit 104 may determine the remaining reduction amount for each target year by subtracting the certainty reduction amount for each target year from the target reduction amount for each target year.

The reception department 102 measures the amount of uncertainty reduction, which is the amount of greenhouse gas reduction caused by activities that are not certain to lead to the reduction of greenhouse gas, within the range of the remaining reduction amount for each target year. Accept to.

The amount of uncertainty reduction may include the amount of greenhouse gas reduction realized by activities performed on properties not owned by the group to which the customer belongs. The amount of certainty reduction is the amount of greenhouse gas reduction due to energy saving activities carried out in properties not owned by the group to which the customer belongs, and the amount of greenhouse gas produced by energy creation activities carried out in the property owned by the group to which the customer belongs. May include at least one of the reductions in.

The amount of uncertainty reduction may include the amount of greenhouse gas reduction reduced by utilizing the power supplied from the renewable energy power generation facility installed in the property not owned by the group to which the customer belongs. The amount of uncertainty reduction is decided to introduce renewable energy power generation equipment when the installation cost when installing renewable energy power generation equipment on a site not owned by the group to which the customer belongs falls below the target price unit price. It may include the amount of greenhouse gas reduction reduced by using the power supplied from the renewable energy power generation facility. The installation cost of renewable energy power generation equipment may be determined by a reverse auction. The target price unit price is calculated by (introduction cost of renewable energy power generation equipment (installation cost + maintenance cost)) ÷ (total power generation amount by renewable energy power generation equipment). The maintenance cost includes the operation management and maintenance cost, and the power conditioner cost (equipment replacement cost every 10 years according to the contract period). The renewable energy power generation facility may be a solar power generation facility, a wind power generation facility, or the like.

The amount of uncertainty reduction is, for example, the reduction of greenhouse gases by contracting with the power generation company to use the electricity supplied from the renewable energy power generation facility constructed by the power generation company on the site owned by the customer. It may include the amount of greenhouse gas reductions reduced by the on-site power purchase agreement (on-site PPA). The amount of power generated by the renewable energy power generation facility may be calculated by multiplying the installation area where the renewable energy power generation facility is installed by a predetermined coefficient.

The amount of uncertainty reduction is, for example, to reduce greenhouse gases by contracting with a power generation company to use electricity supplied from renewable energy power generation facilities constructed on sites other than the site owned by the customer. It may include the amount of greenhouse gas reductions reduced by the Offsite Physical Power Purchase Agreement (Offsite Physical PPA). The amount of power generated by the renewable energy power generation facility may be calculated by multiplying the installation area where the renewable energy power generation facility is installed by a predetermined coefficient. The installation area where the renewable energy power generation equipment is installed may be the target area desired by the customer.

The amount of uncertainty reduction is, for example, the amount of greenhouse gas produced by trading and purchasing electricity supplied from renewable energy power generation facilities built on sites other than the customer's own site in the wholesale electricity market. It may include the amount of greenhouse gas reductions reduced by the Offsite Virtual Power Purchase Agreement (Offsite Virtual PPA) for reduction.

The decision unit 104 is necessary to achieve the target reduction amount for each target year based on the target reduction amount for each target year, the certainty reduction amount for each target year, and the uncertainty reduction amount for each target year. The amount of environmental value certificates purchased is determined annually. The decision unit 104 targets the purchase amount of environmental value certificates corresponding to the remaining reduction amount obtained by subtracting the certainty reduction amount for each target year and the uncertainty reduction amount for each target year from the target reduction amount for each target year. Determined annually. Certificates of environmental value include, for example, J-credit certificates, non-fossil certificates, and green power certificates.

The output unit 106 may output a message inquiring whether or not the uncertainty reduction amount for each year can be achieved at a predetermined timing before the start of each year. The output unit 106 sends a message to the customer inquiring whether or not the amount of uncertainty reduction in the target year can be achieved at predetermined timings such as two years, one year, and half a year before the target year. You may output it.

The reception unit 102 receives from the customer whether or not the uncertainty reduction amount for each target year can be achieved in response to the message. When it is received that the uncertainty reduction amount of the target year cannot be achieved, the determination unit 104 determines the additional purchase amount of the environmental value certificate of the target year corresponding to the uncertainty reduction amount of the target year. As a result, even if the amount of uncertainty reduction in the target year cannot be achieved, the amount of additional purchase of environmental value certificates that can offset the reduction amount can be immediately grasped.

FIG. 2 is a flowchart showing an example of a procedure for determining a target for the amount of greenhouse gas reduction by the determination device 100.

The reception unit 102 receives from the customer the power consumption of the previous year, the GHG emission of the previous year, and the target reduction amount of GHG of the final target year (S100). For example, the reception unit 102 accepts a reduction amount equivalent to a 28% reduction from the base year as the target reduction amount for 2025 as of 2021. The determination unit 104 determines the target reduction amount for each target year up to the target year according to a predetermined algorithm based on the target reduction amount (S102).

Next, the reception unit 102 receives from the customer the certainty reduction amount, which is the reduction amount of GHG caused by the activity that is certain to lead to the reduction of GHG, for each target year up to the target year (S104). The reception unit 102 receives, for example, a reduction amount equivalent to a 1% reduction from the base year as a reduction amount of GHG due to energy saving in each target year. Further, the reception unit 102 receives, for example, a reduction amount corresponding to a 10% reduction from the base year as a reduction amount of GHG due to energy creation.

The determination unit 104 determines the remaining reduction amount of greenhouse gas required to achieve the target reduction amount for each target year based on the target reduction amount for each target year and the certainty reduction amount for each target year. It is determined for each target year by subtracting the certainty reduction amount for each target year from the target reduction amount for each target year (S106).

The reception department 102 measures the amount of uncertainty reduction, which is the amount of greenhouse gas reduction caused by activities that are not certain to lead to the reduction of greenhouse gas, within the range of the remaining reduction amount for each target year. (S108). When the remaining reduction amount is a reduction amount of 17% from the base year, the reception unit 102, for example, has a failure due to an uncertain activity due to energy creation among the reduction amount of the reduction amount of 17% from the base year. As a certainty reduction amount, we accept a reduction amount of 5% from the base year.

Next, the determination unit 104 purchases an environmental value certificate corresponding to the remaining reduction amount obtained by subtracting the certainty reduction amount for each target year and the uncertainty reduction amount for each target year from the target reduction amount for each target year. Is determined for each target year (S110). The determination unit 104 determines, for example, the purchase amount of the certificate corresponding to the reduction amount of 12% from the base year, which is obtained by subtracting the reduction amount of 5% from the base year from the reduction amount of 17% from the base year.

The output unit 106 determines whether or not it is time to inquire about the progress of the uncertainty reduction amount in the target year (S112). The output unit 106 outputs an inquiry message inquiring to the customer whether or not the uncertainty reduction amount of the target year can be achieved at the time of inquiry (S114).

The reception unit 102 receives a response message to the inquiry message from the customer (S116). The determination unit 104 determines whether or not the uncertainty reduction amount for the target year cannot be achieved based on the response message (S118). If it is not possible to achieve the uncertainty reduction amount of the target year, the determination unit 104 determines the additional purchase amount of the environmental value certificate of the target year corresponding to the uncertainty reduction amount of the target year (S120).

The reception unit 102 determines whether or not the current year is the final year (S122), and if it is not the final year, further inquires about the progress of the uncertainty reduction amount in the target year at the timing of the next inquiry.

As described above, according to the present embodiment, the amount of greenhouse gas reduction is appropriately set by dividing the amount of certainty reduction in the target year into the amount of uncertainty reduction in the target year. Then, the uncertainty reduction amount for the target year is set within the range that can be covered by the purchase amount of the certificate of environmental value. As a result, even if the target cannot be achieved, the amount of uncertainty reduction that cannot be achieved can be reliably compensated for by the additional purchase amount of the certificate of environmental value. Therefore, it becomes easier for customers to set a target plan for greenhouse gas reductions.

The determination device 100 sequentially receives the target reduction amount, the certainty reduction amount, and the uncertainty reduction amount from the customer according to a predetermined procedure, and can also determine the purchase amount of the environmental value certificate, so that the processing burden of the determination device 100 can be determined. Can be reduced.
